Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669884, here are decompositions:

5 + 8669879 = 8669884
23 + 8669861 = 8669884
53 + 8669831 = 8669884
107 + 8669777 = 8669884
227 + 8669657 = 8669884
233 + 8669651 = 8669884
257 + 8669627 = 8669884
263 + 8669621 = 8669884

Showing the first eight; more decompositions exist.
